1 Claim.

The present invention relates to conveyors and more particularly to conveyers of the gravity type.

The primary objects of the instant invention are to provide a conveyer of the general character above indicated whose inclination may be adjustably varied; to provide such a conveyer which is simple in construction; to provide such a conveyer which is novel in its structural characteristics; and, to provide such a conveyer which is reasonably economical in manufacture.

An illustrative embodiment of the invention is shown in the accompanying drawings, wherein- Figure 1 is a fragmentary perspective view of the conveyer and its retractable support or carriage;

Figure 2 is a fragmentary front elevational View of the conveyer and its retractable support in its retracted position;

Figure 3 is an enlarged sectional view on line 3--3 of Figure 5;

Figure 4 is an enlarged fragmentary top plan View of the conveyer and its retractable support;

Figure 5 is an enlarged fragmentary side elevational view similar to Figure 2 but showing the retractable support in its conveyer supporting position;

Figure 6 is an enlarged sectional view on lines 6--6 of Figures 4 and '1; and

Figure 'l is a Sectional view on line l-l of Figure 6.

Referring then to the drawings wherein like parts of the structure shown are designated by the same numerals in the several views, the conveyer shown comprises a pair of rails I0, II, there shown as metal channel bars secured together in spaced relationship by means of a plurality of spaced shafts I2, each carrying a free running roller I3 for conveying the work from the receiving end of the conveyer or from its upper o-r left end as viewed in Figure 1 to its lower or right end as viewed in the same ligure.

A retractable support whereby the inclination of the conveyer may be adjustably varied comprises a pair of spaced apart tubular members I4, I5, each secured at its inner or upper end to a transverse tubular member Il disposed intermediately of the opposite ends of the spaced conveyer rails IIi, II, the opposite ends of the members I1 each being rotatably disposed within a channel bar housing I8, each respectively longitudinally slidable on the lower longitudinal portion of a rail I0, II.

The outer or lower ends of each tubular meinber I4, I5 forming the retractable support for the conveyer are secured to a transversely disposed tubular member I9 whose respective ends are each provided with a roller 20 making for mobility of the conveyer.

The lower or receiving end oi the conveyer is provided with a shaft 2| rotatably disposed between the rails I0, II and a tubular membexl 22 secured between the members I4, I5. intermediate its ends has a transverse member 23 secured thereto and secured to the shaft 2l medially of the ends of both.

The channel bar housings IB are each further secured together by means of a tubular member I6 disposed therebetween and an eccentric or cam collar 24 having a handle 25 secured thereto rotatably embraces each outer end of the tubular member I'l, and -when each handle is turned from its position shown in dotted lines in Figure 6 to its position shown in full lines in the same figure, its cam or eccentric engages the under side of a rail Ill, II to adjustably maintain the conveyer in selected inclined position.

Each cam or eccentric 24 is provided with a ball well 26 on its outer surface and each channel housing I8 is provided with a ball 28, operable by means of a helical expansion spring 29, within a Well 30 whereby the cam or eccentric is maintained in unlocked position.

In operation, the upper or left end of the conveyer as viewed in Figure 1, is placed upon an elevated delivering dock or station, not shown, and a selected inclination of the conveyer is then adjustably xed by rotating the cams or eccentrics 24 by means of the handles 25 as hereinbefore explained.

It will thus be seen that the inclination of the conveyer herein illustrated may be adjustably varied and while but one specific embodiment of the invention has been herein shown and described, it will be understood that certain detalls of the construction shown may be altered or vomitted without departing from the spirit of the invention as the same is defined by the following claim.

We claim:

A gravity conveyer having a pair of rails spacedly secured together and means for selectively adiustably varying the inclination of the spaced rails comprising a pair of members each longitudinally slidable on a rail and secured together by a shaft rotatably disposed therebetween. supporting means for the conveyer secured at one end to the shaft, a second shaft rotatably secured between the rails in spaced relation to the x'st shaft, a connecting link secured between the second shaft and said supporting means, and an eccentric collar rotatably carried adjacent each opposite end ci the first shaft whose cammed surface is adapted to be manually rotated into engagement with its proximate rail.
